I added a new service (Service A) and successfully logged in through an external OAuth client.
I want to implement the following scenario: Administrator Bob gives authorization rights (via hub) to "Service A" for user Charlie. After a while, Charlie is transferred to another division and no longer needs access to "Service A". Administrator Bob disables the ability to log in to" Service A " for Charlie.
How can I implement the above scenario using Hub? The use of scopes comes to mind, but I have not been able to figure out how they are configured in the Hub.
